Okay, thanks for the prompt reply @howo. This ...

"Also it's a way of showing my disagreement ..."

... is what I was anticipating. Here on a decentralized blockchain we are, of course, free to do whatever seems best to us. But I for one hope and pray this approach is consistently and heavily discouraged. I don't know where you live or what your philosophy in life is, but I consider freedom of expression to be a cornerstone of our liberties.

As for this ...

"... because he stacked tons of bidbots and I am against that.'

... "tons" ... ??? ... Hmmm, okay, frankly I had not noticed. In general, I understand this is one of the fundamental purposes of our new downvoting mechanism. But ...

By all means @howo, make your disagreements known. Hopefully, as civilly and respectfully as you can manage (as you have done here ...). I am asking you "publicly," however, to reconsider your 100% downvote.

At a minimum, you could consider "sliding it back down the scale" a bit (or a lot!), but still leave something in place as more of a symbolic, rather than a punitive, statement against the use of bidbots.
